Main breaker tripping, dead CIM

[Oblarg]

The crucial bit we noticed is that at our gearing, our breaker is fine unless we stall the CIMs, i.e. while slipping the wheels we have no problem, and the CIMs do not stall on a fully topped-up battery if the compressor is not running.

So, it seems our short-term options (barring changing our gear ratio - if anyone thinks this is really our best solution even with the 2-3 hour investment to get it done, please let me know) are to not turn on our compressor if we are going to be playing defense and to make sure our batteries are in absolute top shape before going out on the field.

Does anyone know if there's a reliable way to test if batteries are actually charged? We have all new batteries this year, but the charge indicator on the charger can be misleading.

(As a side note, I'm wary about swapping two of our CIMs for mini-CIMs, as this could have the opposite of the desired effect by making it absolutely impossible for us to slip our wheels in a pushing match.)
